Media for sandblasting

I have a pressure pot blaster and use extra fine blasting sand at about 90psi, sometimes more. I also have a beadblast cabinet using glass beads. The beadblast cabinet does not work as well when trying to remove thicker paints with a glaze or old runs. I usually sandblast wheels and then run them through the beadblast cabinet which leaves a very nice finish on them.
 
I am with hardtimes on this. Silica seems to work great for me. I have blasted almost all the parts on my truck. I had my rims powder coated after hitting them with 80 grit silica from Thompsons Building materials. $6 bucks a 100# bag. MUST be done outside with a respirator. Days after I find sand in places you would not believe. I do it on concrete so I can reuse three times or so. Have to be careful with the sand break down into dust.
 
I have used silica sand and aluminum oxide for rust removal and as has been discussed always use a good mask around silica sand. I have also used quartz white sand from Toys R Us for cleaning up aluminum with lower air pressure. The sand is inexpensive and does not have the worry about silica dust. Just my experience.
 
Toys R Us, that is great, who would have thought to look there. Maybe they need to have a department for older boys with bigger toys.
